Two hospitalized after shooting on I-580 in Oakland

Oakland police are looking for a motive and suspects in a shooting on an East Bay freeway.

Police say a red Cadillac Escalade with four people inside was coming from an Oakland club around 2:45 a.m. Sunday. It was heading along westbound Interstate 580 near MacArthur Boulevard.

"When he came in contact with an unknown sedan that pulled up alongside the left side of the vehicle," Officer Chad Rishel said. "And witnesses described it as the passenger of the sedan leaned out of the right side and began shooting back at the Escalade."
